FAQs
How does a tankless water heater work, and what advantages does it offer over a traditional storage-tank model?
A tankless (on-demand) water heater heats water only when a fixture calls for it. Cold water flows through a heat exchanger that is warmed by either a gas burner or electric element, delivering hot water in seconds without storing it. Because there is no standby tank, you avoid the heat losses that occur while stored water cools. Homeowners in Petros typically see 20–40 % lower energy bills, enjoy an endless supply of hot water, free up 10–20 sq ft of space, and benefit from units that last 18–20 years—roughly twice as long as many tank models.
What size tankless water heater do I need for my Petros home?
Sizing is based on simultaneous hot-water demand (gallons per minute, or GPM) and the local groundwater temperature. In Petros, incoming water averages 55–60 °F, so we plan for a 60 °F temperature rise to reach a 115 °F shower. Add together the GPM of all fixtures you might run at once: e.g., shower (2.0 GPM) + kitchen faucet (1.5 GPM) = 3.5 GPM. A family of four usually lands in the 6–8 GPM range for whole-house gas units; smaller electric point-of-use models (2–4 GPM) can serve a single bathroom or appliance. Our licensed technician will measure your actual flow rates and recommend the right capacity during the in-home consultation.
How long does a tankless water heater installation take, and what does the process involve?
Most replacements are completed in one day. We start by shutting off water, gas/electric, and draining the old tank. We then mount the compact tankless unit on an exterior or interior wall, run new venting (condensing units use PVC; non-condensing use stainless steel), upsize the gas line if necessary, and install a condensate drain. Water lines receive isolation valves for future maintenance. Finally, we pressure-test, purge air, and program the unit. Electrical models skip the venting and gas work but may require a dedicated 240-V breaker. You’ll have hot water back before dinner in almost every case.
What is the typical cost of installing a tankless water heater in Petros, and will I really save money?
Installed pricing in Petros ranges from $3,000–$4,500 for a whole-house gas model and $2,000–$3,200 for an electric unit, depending on capacity, venting length, and any gas line upgrades. Utility rebates ($200–$300) and the federal 30 % energy-efficient home improvement tax credit (capped at $600 for water heaters) can offset part of the upfront cost. Because tankless units operate only when hot water is needed, ENERGY STAR® reports annual savings of $95–$150 on natural-gas bills; most homeowners see a payback in 6–9 years while enjoying 18–20 years of service life.
What maintenance does a tankless water heater require?
Unlike tank models that risk sediment corrosion, tankless units need their heat exchanger descaled once a year in areas with hard water—Petros sits around 8–10 grains per gallon, so annual service is wise. We flush the unit with a food-grade vinegar solution for 45 minutes, clean the inlet filter screen, inspect the venting, and run diagnostic codes. With proper maintenance, you’ll maintain peak efficiency and keep your manufacturer’s warranty (often 12–15 years on the heat exchanger) valid.
Will a tankless water heater work with my existing plumbing and gas/electric service?
In almost every home, yes. For gas units, we verify that your meter and interior line can supply a higher BTU input—typically 150–199 k BTU. If the line is undersized, we can run a new ¾-in CSST or black iron branch. Electric models need a 60–120-amp 240-V service, so older panels may require an upgrade. Plumbing ties into your existing hot and cold manifolds, and because the heater ramps up instantly, no recirculation loop is required (though we can add one for extra convenience).
